How would it be if they were set for -30 (frozen) or 0 (chilled) about an hour before your due to park up? It would take a long time to reach -15 (frozen) or +5 (chilled) and I’d imagine it would be perfectly safe to eat for quite some time afterwards?? Anyone on here qualified to comments on here?? Maybe no a good idea delivering to iceland as they (allegedly) don’t immediately put it in their freezers?
